Is Your Isuzu Hombre or GM Truck Experiencing Electrical Gremlins?
If you’re dealing with bizarre and frustrating electrical issues in your 1999-2000 Isuzu Hombre or a compatible GM truck like the S10, Blazer, or Silverado, a failing Body Control Module (BCM) is often the culprit. The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of problems that seem unrelated. From power windows with a mind of their own to a security system that won’t cooperate, these issues can make driving your truck a daily annoyance. This isn’t just a minor inconvenience; a faulty BCM can affect vehicle security and safety systems.
Diagnosing and Replacing Your 1999-2000 Isuzu Hombre BCM
A failing BCM doesn’t always trigger a check engine light, making diagnosis tricky. Instead, you’ll notice a pattern of malfunctions in comfort and convenience features. This replacement Body Control Module is the definitive solution to restore your vehicle’s electronic functions to factory specifications. We take the guesswork and hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means no expensive trips to the dealership for programming—it’s ready to install right out of the box. By providing a reliable, VIN-matched 1999-2000 Isuzu Hombre BCM, we help you get your truck back to full operational health quickly and affordably.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The factory anti-theft or security system malfunctioning, causing no-start conditions.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers operating intermittently or at incorrect speeds.
- ✔ False warnings on the instrument cluster, such as a ‘door ajar’ light that won’t turn off.
- ✔ Communication issues with other modules, leading to various diagnostic trouble codes.
Simple Installation Process & Post-Install Requirements
Installation is straightforward for anyone with basic mechanical skills. The BCM is typically located behind the dashboard, often near the center console or on the driver’s side. Once you’ve swapped the module, most functions will be restored immediately. However, due to the complex integration of vehicle systems, some models may require additional steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to synchronize the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some vehicles, a brake pedal position sensor recalibration might be needed to ensure proper operation of the brake lights and traction control system.
We make the process easier with a no-core-charge policy. You can keep your old module without any extra fees or the hassle of shipping it back. This is the most direct path to fixing the electrical issues in your 1999-2000 Isuzu Hombre BCM or other compatible GM vehicle.

No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and the module will arrive ready to install.
Where do I provide my VIN?
You can add your VIN to the order notes during checkout. If you forget, don’t worry—we will contact you via email to request it before we program and ship your part.
Is this installation plug-and-play?
For most vehicles, it is. You disconnect the old BCM and connect the new one. However, as noted, some vehicles may require an airbag system sync or brake pedal position relearn, which requires a professional scan tool.
Do I need to send my old BCM back?
No. This product comes with no core charge, so you can keep your original module without any additional fees or hassle.
What happens if my airbag light comes on after installation?
This indicates that the new BCM needs to be synchronized with your vehicle’s airbag module (SDM). A qualified technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool to resolve this.
Will this BCM fix my specific electrical problem?
If your vehicle’s symptoms match those of a failing BCM and the issue has been properly diagnosed, this part is the correct solution. It is designed to restore all factory body control functions managed by the BCM.
